Man Rides World Smallest Bicycle

Just saw this interesting video clip on a friend's facebook update. Sharing it out here.

Video shows an adult taking out a small item from his bag. 

How big can that stuff come out from his bag be? 

NO bigger than his palm.

& 

Guess what he did next?

He started sitting & riding on that stuff he took out of his bag.

I thgt he is Doraemon taking out wonderful things from his stomach. 

I don't think i can fit into that bike, not unless it break apart before I can set my feet on it. :D
